[neon/qt/qtdeclarative/Neon/release] debian: Use symver directive to catch all private symbols at once.

[Dmitry Shachnev]

Git commit 3bdaae38bbe5bd5b469a55d06d60f0f01bcbc2f3 by Dmitry Shachnev.
Committed on 21/05/2022 at 21:40.
Pushed by jriddell into branch 'Neon/release'.

Use symver directive to catch all private symbols at once.

We don't need to track additions and deletions of private symbols,
because they have a dependency on the exact upstream version.

Thanks to Pino Toscano (who did the same in Qt 6) for the idea!
